Ah you beat me to it...
A fix has gone in tonight around this, I have only just finished testing from a few lines to see if its working.
The information provided in this thread helped track this issue down, so thanks to everyone that gave me details of the issue and pm'ed me account details and answered the many questions I had.
If anyone is still having issues i would really like to know so we can get on top of that as well.
Sorry I didnt post an update saying it was going ahead tonight, but I wanted to test it before hand.
Glad the issue seems to be fixed so far though.
@freitas are you able to access your bill now as well?
Paul
